Well, set up a proportion first.
x/60 = 15/100
solve the proportion to get the amount of money it was marked up: $9.
Add 9 to 60,
The final price would be $69.
Simple,

to find the rate of selling price price based on cost....-rate of cost+rate of the markup..

In work..

S%=C%+M%

The cost is $60 and C is 100%, also you know M%=15%

S%=100%+15%=115%

Rate of the selling price=115%

Step 2: Find the selling price

S=S%*CS=115%*$60S=1.15*60=$69

The selling price at a 15% markup is $69.

Thus, your answer.
